HARDWARE FOR SWINGING SLIDING STORM SASHES Original Filed May 12. 1950 ATTORNEYS Patented Oct. 6, 1953 HARDWARE FOR SWINGING SLIDING STORM SASHES Harold E. Graves, Jr., Akron, Ohio, assignor to Brown-Graves Company, Akron, Ohio, a corporation of Ohio Original application May 12, 1950, Serial No. 161,526. Divided and this application October 1'1, 1951, Serial No. 251,765

2 Claims. (Cl. 20-42) This invention relates to casement windows, and in particular to the hardware which includes a radius arm for swinging the window durin opening, the present application being a division of my application Serial No. 161,526, filed May 12, 1950, now Patent No. 2,603,844, issued July 22, 1952.

In the type of window construction described in my aforesaid application, the window sash is mounted or removed from a window frame by simple manipulation, and without employing extraneous fastenings of semi-permanent nature, and it has been a shortcoming of such construction that the installation lacked rigidity, and sagging interfered with the sliding action required as an incident to turning of the sash by the radius rod. I have found that the difliculties are effectively eliminated by providing radius rods having a normally bowed form, reinforced by a central, longitudinal rib.

It is therefore an object of the invention to improve the stability and effective lodgment of casement windows of the swinging-sliding type.

In the drawings:

Fig. 1 is a view in side elevation, showing a radius rod pivotally carried on a plate to be attached to a sash,

Fig. 2 is a sectional view taken on the line 22 of Fig. 1, and

Fig. 3 is a perspective view of the device of Fig. 1 showing its adaptation to a casement sash, with parts shown in broken lines.

Referring to the drawings by characters 01' reference, there is shown in Fig. 3, a window frame, sill, etc., indicated generally by the numeral l0. Located in a groove or mortise in the sill is an anchoring trough II, in which is adapted to slide a rider |2 comprising a pair of spring leaves l3, I4 of the type shown and described in Patent No. 2,051,638. To this rider is pivoted, by means of a pin IS, a bar H, which is secured by screws l8 to the under side (or top side) of a swinging sash l9 shown partly in broken lines.

A radius bar 2| is pivoted at its end to an intermediate part of bar I! by a pin 22. The other end of bar 2| has a fixed pin 23 adapted for lodgment in an opening in a strip 24 integral with the bottom of channel II and level with the top thereof. Strip 24 is secured to the sill by screws 26. Channel II has an outwardly struck tab 21 providing for run-01f of water.

In operation, as sash I9 is urged outwardly of the window frame, rider I2 is urged along channel H and the sash is constrained to turn about pivot 22.

As seen in Fig. 1, the radius bar 2|, in its normal form, when not mounted in the window frame, is curved away from bar N. This may be provided in a rolling operation, in which suitably formed rolls produce a longitudinally extending rib 28. A radius bar of this form has a permanent bow and provides a tightening action in the assembled sash which is of particular advantage in sliding, swinging easements such as shown, the action being smooth and free from jamming, and not subject to sag.

What is claimed is:

1. A casement window having hinge pins adapted for sliding motion along upper and lower channels in a window frame, a link pivoted intermediate said window and having a pin adapted to be anchored in said window frame, said link being curved away from its point of pivoting on said window and having a longitudinal groove on its concave side and a longitudinal rib on its convex side tending to maintain the link in its curved form.

2. For use with a casement window of the swinging-sliding type, a manipulating element comprising a first bar, a second bar pivoted on one side of one of its ends to an intermedlate point of said first bar, a pin extending from said second bar on the side opposite said first bar, said second bar having a longitudinal corrugation and having a normal form in its unstressed condition. curving away from said first bar.
